Subject: [PATCH v3 2/2] arm64: dts: qcom: x1e80100-yoga: Update panel bindings

From: Rob Clark <robdclark@...omium.org>

Use the correct panel compatible, and wire up enable-gpio.  It is wired
up in the same way as the x1e80100-crd.

Note that the power-source differs from the CRD.  Figured that out by
diffing $debugfs/gpio.
